Abstract

In order to study the viral etiology of human brain tumors, attempts were made to isolate cytopathogenic agents from human brain tumors by the tissue culture of tumor tissues and by the mixed culture of tumor tissues with HeLa cells. Five glioblastomas, a mixed form of glioblastoma and fibrosarcoma, two astrocytomas, two ependymomas, two meningiomas, an oligodendroglioma, a spongioblastoma polare and a choroid plexus papilloma were studied. In the tissue culture, besides the cells which appeared to be the tumor parenchymal cells, varying amounts of fibroblastic cells appeared in all the tumors tested and they increased with the prolongation of the culture period. In any of the tumors tested, no cytopathogenic agents were detected by either the culture of tumor tissues or the mixed culture of tumor tissues with HeLa cells. From the virological point of view, the significance of these negative results was discussed.
